Skype Awesome for chatting or video conferencing with international friends. Actually, it also has a telephone book (yellow pages) directory of almost every city in the world. And they are always coming out with new features. neat!

SodaSnap Postcards Simple and fun! You can turn any photo into an e-card and send it. It also has some quick and easy photo editing features. App space might be a concern.

Facebook Who can live without Facebook these days? Everyone I know is on there from my grandma to college professors, and my grammar school friends! I love reconnecting with people I haven't seen in years and years! In my opinion, that's the best feature of this app. I could care less that Jack commented on Janes status. Then again, I'm not complaining. It's free, but I don't think it's a completely philanthropic endeavor either. Slowly but surely, Facebook is pushing to be able to sell user information to advertisers and much, much, more. Privacy issues, here we come!

Yelp I'm a huge fan of Yelp because of all of the user reviews. So many people participate on this site, that the truth about a place you might want to go is actually revealed. Not to mention, if you are just looking for something new to do, there are tons of great ideas!

Meetup Do you use Meetup? Well, now you can have it on your iphone. What could be better? If you are not familiar with the website, it's a place where people form groups and post events and "meet up!" It has everything from pick-up soccer games, to groups that go to the Opera. Enjoy!
